In a geometric series, the common ratio \( r \) describes how each term relates to the previous term. If each term is 21% less than the previous term, this indicates that each term is 79% of the previous term.
In mathematical terms, this can be expressed as:
\[
r = 1 - 0.21 = 0.79
\]
Thus, the value of \( r \) for this geometric series is:
\[
\boxed{0.79}
\]
